League champs Tyrone take on Antrim
League champions Tyrone are in action today in the Ulster semi-final against Antrim at Casement Park.
Mark Harte, son of Tyrone manager Mickey Harte, makes his first championship start, joining Peter Canavan and Owen Mulligan in the full forward line.
Kevin Hughes and Gerard Cavlan will form a new midfield partnership - taking over from the injured Cormac McAnallen and Sean Cavanagh.
Meanwhile, Antrim shows only one change from the side that disposed of Cavan in the quarter-final shocker.
John McKeever comes in for Colm Brady.
